    Abstract: A semiconductor device includes a semiconductor substrate and a trench isolation. The trench isolation is located in the semiconductor substrate, and includes an epitaxial layer and a dielectric material. The epitaxial layer is in a trench of the semiconductor and is peripherally enclosed thereby, in which the epitaxial layer is formed by performing etch and epitaxy processes. The etch and epitaxy process includes etching out a portion of a sidewall of the trench and a portion of a bottom surface of the trench and forming the epitaxial layer conformal to the remaining portion of the sidewall and the remaining portion of the bottom surface. The dielectric material is peripherally enclosed by the epitaxial layer.

    Abstract: The present disclosure relates to an image sensor having a photodiode surrounded by a back-side deep trench isolation (BDTI) structure, and an associated method of formation. In some embodiments, a plurality of pixel regions is disposed within an image sensing die and respectively comprises a photodiode configured to convert radiation into an electrical signal. The photodiode comprises a photodiode doping column with a first doping type surrounded by a photodiode doping layer with a second doping type that is different than the first doping type. A BDTI structure is disposed between adjacent pixel regions and extending from the back-side of the image sensor die to a position within the photodiode doping layer. The BDTI structure comprises a doped liner with the second doping type and a dielectric fill layer. The doped liner lines a sidewall surface of the dielectric fill layer.
